Dan,
I know that cur and his fat ass master.
Same chit during the king season. I lost a nice king from that dog. A seal taking your fish is acceptable, but a dog releasing your fish for you is a no no.
I love dogs but never seen a well mannered dog on the river. Except for the ones on a leash tie to a tree, still there is the constant barking and yelping. I took my dog out once and he is worst than any of the dogs I encountered. Once is it for him unless we go to some remote hole where no people is around. And I encourage dog owners to do the same. Its suppose to be a relaxing activity.
